PRIMARY DISPLAY SYSTEM -ELECTRONIC CHECKLIST OVERVIEW
General
Checklists contain data necessary for the flight crew to operate the airplane in normal conditions and to help with non-normal conditions.
The flight crew completes the electronic checklist item by item on a READ and DO basis. These are the three types of checklists:
*
Normal checklists (for example, PREFLIGHT and BEFORE START)
*
Non-normal checklists related to an EICAS message (for example, ENG FAIL L and FIRE APU)
*
Non-normal checklists not related to an EICAS message (for example, GEAR LEVER LOCKED DN and VOLCANIC ASH).
Normal checklist are organized by phase of flight. The flight crew uses them to verify that important procedural steps have been done.
Non-normal checklists contain steps to correct a condition. A square box shows in front of an EICAS message when the message is related to a non-normal checklist and the checklist is not complete. There are also non-normal checklists not related to an EICAS message. These are called unannunciated checklists.
Electronic Checklist Operation
Normal and non-normal electronic checklists show on any multifunction display (MFD). Push the CHKL switch on the display select panel (DSP) to show a checklist.
Only one checklist shows at a time. This checklist can show on more than one display unit, but only one cursor control device (CCD) can control the checklist.
